חברים,
כפי שציינתי, ככה נהוג בכבלים 1.3,
יתכן וב 1.4 זה כבר שונה.
וכמו שציינתי יש חריגים לפה ולפה.
אבל אתגרתם אותי ולכן חיפשתי לבדוק אם זיכרוני מטעה אותי:
אני מצטט כאן מWIKI:
"With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, an HDMI cable can reach lengths of up to 15 meters (49 ft)."
מתוך האתר של ארגון HDMI (שם ממליצים עד 10 מטר, אבל לא מצוין אם זה גם תקף ל 1.4):
"
Q. Does HDMI accommodate long cable lengths?
Yes. HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. We have seen cables pass "Standard Cable" HDMI compliance testing at lengths of up to a maximum of 10 meters without the use of a repeater. It is not only the cable that factors into how long a cable can successfully carry an HDMI signal, the receiver chip inside the TV or projector also plays a major factor. Receiver chips that include a feature called "cable equalization" are able to compensate for weaker signals thereby extending the potential length of any cable that is used with that device.
Q. How do I run HDMI cables longer than 10 meters?
There are many HDMI Adopters working on HDMI solutions that extend a cable’s effective distance from the typical 10 meter range to much longer lengths. These companies manufacture a variety of solutions that include active cables (active electronics built into cables that boost and extend the cable’s signal), repeaters, amplifiers as well as CAT5/6 and fiber solutions.

לגבי 1.4 מצאתי את זה:
"HDMI 1.4 is up to 50 ft with better quality cabling. My HDMI 1.3b cable is 30ft and works successfully, but when I added a coupler with another 6ft of 1.3b, the signal failed, my monitor was showing half of the pixels. Couplers and similar items greatly reduce the signal."
מצאתי לכך עוד סימוכין באתרים בחו"ל ובארץ.
